Crystal Bell ★

Taken all the way down to base materials, one Crystal Bell is 3 crafting steps deep and needs 3 intermediates — Birch Lumber ×1, Titanium Alloy Ingot ×1 and Titanium Nugget ×1 — which resolve to 6 distinct raw materials totalling 15 units, plus 15 crystals.

That bill outweighs 6,735 of the 13,602 recipes tracked here and 730 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 12 are burned by the intermediates, so the real crystal cost is 5 Wind Crystal, 4 Fire Cluster, 4 Fire Crystal and 1 other kind.

The chain crosses two disciplines — Blacksmith to Lv 60 and Carpenter to Lv 58 — so no single class can finish it unaided.

All 6 raw materials are gathered, and one of them is time-gated: Sphalerite (2:00, 6:00, 10:00, 14:00, 18:00, 22:00). The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

Of the intermediates, Titanium Nugget has the widest use: 112 recipes call for it, spanning six of the eight crafting classes.
